ADDED Requirements

Requirement: Check action does not modify player chip count or bet contribution

When a player checks, the system SHALL only mark the player as having matched the current bet level without deducting chips or modifying their currentBet value.

Scenario: Check with zero current bet

WHEN the current bet is 0 and Player A checks
THEN Player A's betMatched becomes true, currentBet remains unchanged, and chip count remains unchanged

Scenario: Check after matching previous bet

WHEN Player A has already called a bet of 100 (currentBet = 100) and the next player checks (no raise occurred)
THEN Player A's state remains unchanged except betMatched is set to true

Requirement: Betting round completes when action returns to last aggressor

The system SHALL end a betting round when all active players have matched the current bet and action returns to the position of the last player who raised or opened betting.

Scenario: Pre-flop BB option (no raises)

WHEN SB posts 10, BB posts 20, and all players check around back to BB
THEN BB may check without posting additional chips, and the betting round completes

Scenario: Raise requires action to return to raiser

WHEN Player A raises to 100, Players B and C call, and Player D checks
THEN the round does not complete until Player A either checks or faces no further raises

Requirement: All-in players are excluded from betting round completion check

When determining if a betting round is complete, the system SHALL only consider active (non-all-in) players for the "all matched" condition.

Scenario: Active player skipped by all-in completion bug

WHEN Player A bets 100, Player B goes all-in for 50, and Player C has not yet acted
THEN the betting round does NOT complete; Player C must act before the round advances

Scenario: Single active player ends round

WHEN all players except one have folded or gone all-in
THEN the betting round completes immediately and the game proceeds to the next stage

Requirement: Turn advancement skips non-active players correctly

The system SHALL advance turns to the next player with status === 'active', skipping folded and all-in players.

Scenario: Folded player is skipped

WHEN Player A folds and it's their turn position
THEN the turn advances to the next active player clockwise from Player A

Scenario: All-in player is skipped during betting

WHEN Player B goes all-in during a betting round
THEN subsequent turns skip Player B and advance to the next active player
